The whole country did not partake in the Revolutionary War. Just a minor percentage did. No matter how bad the government schools get or how bad society in general becomes, they will always be a minor percentage ready to take up arms to defend our freedom. I believe the framers referred to them as being a well armed and regulated militia. By armed I believe they also were referring to being armed with the wisdom of knowing the actual costs involved with securing that freedom. Unfortunately quite a few people have died in Georgia. So those costs were great. Hopefully when the fog of war is lifted we will completely understand the factors causing this engagement.
Good point. Just a few were willing to die for that freedom, the rest were content to sit under the protection of the King.
Also, alot of the battles were won by the Scots Irish coming down from the Appalacians and they were already ticked off at Britain. So they had some grudges to settle.
